Sante Monachesi (10 January 1910 – 28 February 1991) was an influential Italian painter and sculptor who played a pivotal role in the Futurist movement. Born in Macerata, he introduced Futurism to the Marche region, founding the Movimento Futurista nelle Marche (also known as the Umberto Boccioni Futurist Group) in 1932. Monachesi's career spanned several artistic phases, transforming from high-speed Aeropainting to postwar expressionism and groundbreaking space-age plastic sculptures. Inspired by Umberto Boccioni’s writings, Monachesi experimented with diagonal, spiralist, and aerodynamic shapes. As a prominent figure in the Aeropittura (Aeropainting) scene, his work was showcased at major international stages including the Venice Biennale (1936, 1938) and the Paris World Expo (1937).

Following World War II, his style shifted toward expressionist and Fauve painting. He became a core part of the "Balduina" group within the Scuola Romana and developed a distinct figurative language defined by broad color planes and synthetic outlines, heavily influenced by his time spent in Paris.

Monachesi's most innovative period involved avant-garde plastic sculptures. He was one of the first artists to introduce materials like Perspex (polymethacrylate) and rubber foam into contemporary fine art. Captivated by the 1969 Apollo Moon landing, he founded the Agrà Movement, an artistic current dedicated to exploring "Zero-G" (the absence of gravity) to conceptually free humanity and art from physical boundarie
